Title: Improvements in or relating to rotary meters for measuring mass flow of fluids
IPC: H05K13/04
Filed: 1963-05-25
Abstract: 1,084,520. Rotary mass-flow meters. R. MAURER. May 22, 1964 [May 25, 1963], No.20957/63. Heading F1F. A rotary fluid mass-flow meter of paddle wheel type, comprising guide vane means for imparting a swirl to the fluid, means for measuring the torsional reaction of the fluid on the guide vane means, and a freely rotatable paddle wheel for determining the swirl velocity of the fluid, includes a by-pass by-passing the guide vane means and a mixing chamber upstream of the paddle wheel into which both the by-pass and the guide vane means discharge. As shown in Fig. 1, helical guide vanes 18 fixed to a shaft 17 are mounted within a sleeve 25 supported by axially extending vanes 28 within an enlarged diameter portion 12 of the meter casing to provide an outer annular by-pass chamber 27 whose inlet 31 is controlled by a valve member 29 movable in response to fluid flow by a rack and pinion (not shown) and a servomotor 30. The inlet 31 being closed when flow is a minimum and opened to its maximum when flow is a maximum. The shaft 17 upstream of the guide vanes 18 carries a torque meter 15 whose output is fed to a computer 35 and on a reduced diameter portion downstream thereof is a freely rotatable paddle wheel 21 whose speed is recorded by a pick-up 34 feeding signals to the computer 35 so that mass flow is measured by the quotient of the swirl velocity and torque reaction. The provision of the by-pass and the valve 29 controlling the flow therethrough is said to maintain the accuracy of the motor over a wide range of flow values. In a modified construction, the valve member 29, and servomotor 30 are removed and the sleeve 25 is replaced by a spring-loaded sleeve separated from the vanes 28. At low rates of flow the spring urges the sleeve into seating engagement with an annular projection on the meter casing to close the inlet 31. As the flow rate increases the sleeve is moved away from the projection to increase the flow through the by-pass.

Filed: 1977-05-20
Abstract: 1534259 Inserting electrical components into circuit boards UNIVERSAL INSTRUMENTS CORP 20 May 1977 [24 May 1976] 21399/77 Heading B3A Apparatus for inserting electronic components into a circuit board has an inserter assembly 200 rotatable from a drive position to a feed position where a feeding sub-assembly 400 feeds a component along the longitudinal axis of the inserter assembly into the inserter and subsequently the inserter assembly is rotated back to the drive position where it is driven along its longitudinal axis to insert the component into the board. The inserter assembly comprises a pair of pivotally mounted guides 208, a pair of blades 204 and a plunger 226 all of which are mounted on a slide 332, Fig. 6. The inserter assembly is rotated to and from its feed position (shown in phantom in Fig. 2) by a pneumatic cylinder which is connected to a shaft of the assembly by a rack and pinion. In operation, an electronic component is fed down a shoot 108, 110 to the feed sub-assembly 400 and is retained therein by stops 430, 432 and fingers 462, 464 on spreaders 420, 422 pivotally mounted at 416 and 418 respectively. After the inserter assembly has been rotated to its feed position, a piston 460 advances a slide 442 which causes cam surfaces 454 thereon to pivot the spreaders 420, 422 and cause fingers 444, 446 to spread the leads of the component. Further movement of the slide 442 causes a platform 448 to contact the bottom of the component so that it is clamped between the platform 448 and plunger 226 and transferred to the inserter assembly 200 where it is held between the blades 204. The assembly 200 is now rotated to its drive position and its slide 332 lowered so that the guides 208 close around the blades 204 and come to rest on the circuit board. The plunger 226 is now lowered to push the component into holes in the board.

Abstract: 1,063,957. Inverting food trays. AMERICAN MACHINE & FOUNDRY CO. May 25, 1964 [June 5, 1963], No. 21497/64. Heading B8E. A tray T carrying a food portion is inverted by device 2 so that the portion is discharged from the tray. Thus the tray carrying the food portion is received between the double bars 20 pivoted at 22 so that the tray is carried by the guides 24. The arms 20 are given an oscillation so that the tray which is received in position I is swung to position II to discharge the portion down shoot 80 (not shown) whilst retaining the tray within the arms 20. The arms 20 are then reversed to position III so that the tray is able to slide out of the grooves 24 of arms 20 and be discharged empty down shoot 84 (not shown). The arms then move to position I to complete the cycle. Motor control.-The requisite movement of shaft 22 carrying arms 20 is achieved by a motor which drives driving shaft 48 and thereby drives shaft 22 through the linkage 46, 44, 42 and gears 38 and 36. The movement of the motor and the control of the electric circuit is made by switches 28, 68 and 74: which switches are controlled respectively by the arrival of the tray in the guides 24 of arms 20; by the movement of bar 52 pivoted at 54 and controlled by follower 56 operated by cam 58; and by disc 72 secured to shaft 48. The movement of shaft 22 and of the trays is timed with that of a fat fryer which receives the food portions from the trays.

Abstract: Surfaces of glass, ceramic, metal, wood, masonry and organic resins may be coated with aqueous solutions of a mixture of silanes containing allyl and/or methallyl groups, resorcyloxy groups and alkylene glycol residues attached to silicon, with the optional addition of vinyl and chloroalkoxy groups, all within certain defined proportions (see Group IV (a)).  The compositions may also contain the monomethyl ether of ethylene glycol and is preferably used in concentrations of 0.1 to 10% by weight.ALSO:A composition for treating glass fibres comprises an aqueous solution of a mixture of silanes containing allyl and/or methallyl groups, resorcyloxy groups and alkylene glycol residues attached to silica, with the optional addition of vinyl and chloroalkoxy groups, all within certain defined proportions (see Group IV (a)). The concentration of silanes may be from 0.1-10% by weight, and the compositions preferably also contain the monomethyl ether of ethylene glycol.  The treatment is particularly useful for glass cloth to be used in resin-bonded laminates.  After application, e.g. in a bath, the cloth is heated to 110-150 DEG  C.  It is also stated that the compositions may be used on organic fabrics such as cotton, wool, nylon and rayon.ALSO:The invention comprises a water-soluble mixture of organosilicon compounds, the mixture having the empirical formula <FORM:0832224/IV (a)/1> in which R is hydrogen or methyl, a is 0.25 to 1, b is 0 to 0.75, c is 0.25 to 1.5, d is 0.6 to 3.25, e is 0 to 0.1, x is 1 or 2, y is 0 to 0.375, R1 is hydrogen or an alkyl radical of less than 4 carbon atoms, and Z is a chloroalkoxy group of less than 5 carbon atoms; there being an average of 0.66 to 1 hydrocarbon radicals per silicon atom and only one hydrocarbon radical attached to any one silicon atom in the mixture.  The materials are best prepared by reacting allyl and/or methallyl trichlorosilane, or a mixture of one or both of these silanes with vinyltrichlorosilane, with resorcinol, and then reacting with ethylene or diethylene glycol or a lower monoalkyl ether thereof. Any remaining chlorine can be neutralized with an alkaline material such as ammonia or sodium acetate, or by reacting with an alkylene oxide which will introduce chloroalkoxy groups attached to silicon.  The order of these reactions may, however, be changed, and, instead of the chloro derivatives, allyl, methallyl and vinyl methoxy or ethoxy silanes may be used.  The reaction may be carried out under reduced pressure or in the presence of a hydrogen halide acceptor and a water-miscible solvent is preferably used, e.g. alcohols, dioxane, alkylene glycols and their ethers.  The mixture is useful in dilute aqueous solutions for treating glass, particularly glass fabric to be laminated, other fabrics such as cotton, wool, nylon and rayon, and ceramics, metal, wood, masonry and organic resins.
